Fire shields must comply with all applicable requirements for opening protectives in Chapter 14B-7.
Fire shields must have an opening sash having a clear area not less than one-half the area of the exit doors leading from the buildings to the vestibule or balcony and must be located not less than four feet (1219 mm) above the floor and not more than six inches (152 mm) below the ceiling of the vestibule or balcony, arranged to open automatically in case of fire to the full limit and to be held securely in such open position. Provision must be made for the manual opening or closing of the sash.
The automatic opening of the sash must be actuated by devices located inside the building within five feet (1524 mm) of the door from the building to the vestibule or balcony and located also on the ceiling of the vestibule or balcony. Such devices must operate as a result of rate of temperature rise or when the surrounding air reaches a temperature of 120°F (49 °C).

Testing must be performed by an individual or organization acceptable to the fire code official. Reports of the testing must be filed with the fire code official by June 30 of each year.
